Embodiment Construction

[0012] The structure of the present invention will be described in detail below.

[0013] As the electroplated steel sheet of the base of the aluminum-containing lead-based alloy steel plate in the present invention, the content of aluminum in the electroplated film is 5-75% of the aluminum-plated lead-based alloy steel plate, such as 55% aluminum-lead-based alloy plated The steel plate is the most representative. Generally speaking, the silicon Si in the electroplated film of this aluminum-plated and sub-lead alloy steel plate is more than 0.5% of the aluminum Al content; In other words, it generally means that the aluminum content is about 50 to 60% of the aluminum and sub-lead alloy steel plate (in the following description, it means the aluminum and sub-lead alloy steel plate of 55%), and the electroplated film usually contains 1 to 3% About silicon Si, as described below, although the effect of improving the characteristics of the present invention can be sufficiently obt...

Abstract

A surface treating agent for metallic material contains the water resin (urane resin or acrylic resin) with carboxy and acid-amine, the compound of metals chosen from Al, Mg, Ca, Zn, Ni, Co, Fe, Zr, Ti, V, W, Mn and Ce, and the surface treating agent (silicic acid, silicate, colloidal SiO2, or organic silane) containing silicon compound, but not Cr. A steel plate which is treated by said surface treating agent and plated by aluminium-plumbo alloy is also disclosed.

Description

technical field [0001] The present invention relates to a chromium-free metal surface treatment agent for making non-painted aluminum-lead alloy steel sheets such as building materials or household appliances have alkali resistance, calendering and setting properties, and corrosion resistance, and the use of the treatment agent for surface treatment aluminum-plated sub-lead alloy steel plate. Background technique [0002] Aluminum-plated lead-based alloy steel sheets, especially 55% aluminum-lead-plated alloy steel sheets, are often used for building materials such as eaves building materials or outer wall building materials of buildings, and pillars for agricultural insulation rooms due to their excellent corrosion resistance. Civil engineering products such as guard rails, sound insulation walls, and drainage ditches; household electrical appliances, industrial machines, etc. are not used for painting. When used as a building material, since the electroplated steel plate ...
